Post-quantum wallet

The wallet built for the quantum age

Claak is a self-custody wallet for Base, Solana, and Bitcoin. Your money is guarded by a post-quantum key that a future quantum computer can't break. This guide shows you everything it can do.

Get started in minutes

Install the extension, set a password, and save your recovery phrase. That's it.

Install Claak

Add the extension to Chrome, Brave, or Edge, then pin it to your toolbar.

Create a new wallet

Pick a strong password. It encrypts your keys on this device only — nothing is sent to a server.

Save your recovery phrase

Write down the 12 words and keep them offline. They are the only way to restore your wallet.

Add some funds

Use Receive to get your address, or grab test coins from the built-in faucet links while on a test network.

Already have a wallet? Choose Restore on the welcome screen and enter your 12-word phrase, or load an encrypted backup file.

Everything Claak can do

A full tour of the wallet, grouped by what you want to get done.

Your wallet

Quantum Vault

Your main account holds your money and is controlled by a post-quantum key, not a normal one.

Execution wallet

A small helper account pays the network fees. You can see it any time, so nothing is hidden.

Multiple accounts

Make as many accounts as you like, name each one, and switch between them in a tap.

Many chains

Switch between Solana, Base, and Bitcoin from one place. Each shows its own balances.

Security levels

Pick Standard for everyday use or Maximum for a larger safety margin on your biggest holdings.

Activity log

See your recent transactions and open each one in a block explorer to check it on-chain.

Move money

Receive

Show your address and a QR code so anyone can send you coins or tokens.

Send

Send ETH, SOL, or USDC. Claak checks the address and shows the value in dollars first.

Multiple tokens

Hold SOL on Solana, plus ETH and USDC on Base. Tap between them to see each balance.

Live prices

Each token shows its current dollar value, so you always know what you're holding.

Confirm before you send

A clear review screen shows who, how much, and on which network before anything leaves your wallet.

Revoke approvals

Cancel any standing token permission you gave an app, so it can no longer touch your funds.

Swap & trade

Instant swap

Trade one token for another in a single step, at the best price across exchanges on Base.

TWAP orders

Split a big trade into smaller pieces over time, from 15 minutes up to 7 days, to get a smoother price.

Open orders

Watch your active TWAP orders fill, and cancel any of them whenever you want.

Wrap & unwrap

Turn ETH into WETH and back, one-to-one, right inside the swap screen.

Slippage control

Set how much price movement you'll accept, so a swap won't fill at a price you didn't expect.

Bitcoin

Bitcoin Vault

A quantum-safe Bitcoin account that hides your key behind a fresh address on every receive.

Fresh receive address

Each time you receive Bitcoin you get a brand new address, which keeps your activity private.

Send Bitcoin

Enter an address and amount to send. Your change returns to a safe, hidden address automatically.

Connect to apps

Connect to dApps

Use Claak with apps on the web through WalletConnect or the standard browser connection.

Choose your mode

For each app, pick your Quantum Vault or a standard wallet, so everything stays compatible.

Sign messages

Approve sign-in requests and typed messages from apps, with the full details shown first.

Approve pop-ups

A small window shows exactly what an app is asking for before you say yes.

Keep your wallet safe

Strong protection by default, plus extra controls when you want them.

Password lock

Your keys are encrypted on this device with your password. No cloud, no account, no server copy.

Biometric unlock

Open your wallet with Touch ID or Windows Hello where your device supports it.

Auto-lock

The wallet locks itself after a short time idle, so a left-open browser stays protected.

Encrypted backup

Save a single encrypted file you can use to restore your wallet in any browser later.

Recovery phrase

A standard 12-word phrase you can reveal any time after confirming your password.

Lock any time

One tap locks the wallet straight away when you step away from your computer.

Account protection (optional)

Allowlist

Only let funds go to addresses you've approved in advance.

Spend limits

Cap how much can leave per transaction and per day, so a slip-up stays small.

Withdrawal timelock

Large or unlisted sends must be announced and wait, giving you time to stop anything wrong.

Recovery owner

Add a trusted backup key that can step in if you ever lose access to your account.

This is an early release. Some contracts are not yet audited. Start with small amounts, and always keep your recovery phrase written down and offline.

Step-by-step guides

The most common things you'll do, in order.

Common questions

Short, clear answers to what people ask first.

What does "post-quantum" mean here?
A future quantum computer could break the keys most wallets use today. Claak controls your money with a Falcon key, a type of key that those computers can't break. So your funds stay safe even as the technology changes.
Does Claak hold my keys?
No. Your keys live only on your device, encrypted with your password. There's no account and no server copy. You're in full control, which also means your recovery phrase is the only backup.
What is the Execution wallet for?
Networks charge a small fee for each transaction. The Execution wallet pays those fees so your main Quantum Vault stays clean and protected. You can top it up and see its balance any time.
What if I lose my password?
Restore the wallet using your 12-word recovery phrase, then set a new password. Without the phrase or an encrypted backup, no one — including us — can recover it. Keep the phrase safe and offline.
Which networks does it support?
Solana, Base, and Bitcoin. Use the network switcher at the top to move between them. Some networks run in test mode for now, marked with a badge so you always know.
Can I use it with other apps?
Yes. Connect through WalletConnect or the standard browser connection. For each app you can choose your Quantum Vault or a standard wallet, so everything works smoothly.
